An atmospheric river is expected to sweep into the Bay Area on Tuesday night and Wednesday morning, forecast to pound the area with rain, fell trees and bring potential flooding to every county but Solano.

The possible destructive impact is cause for special concern in one part of Pleasanton. Houses sit on a cliff that is already eroding and could further destabilize in the storm, residents along Foothill Road near Arroyo Creek told KRON4 this week.

Erosion has been a threat along the creek for years now. In March 2017, heavy rainfall in the area led to erosion that created dramatic, alarming-looking backyard cliffs.

In one affected home, 25 feet of yard fell away, creating a cliff that dropped down to the creek just a few feet from a backyard swimming pool, CBS reported at the time.

This week, a city spokesperson told KRON4 the problem had been fixed, but some residents say further action is needed from the Zone Seven Water Agency, which stated in 2017 that it does not own the section of creek most affected by the erosion.

“Pray for us that it’s going to be good over the week. Otherwise, I don’t know what this is going to look like come this weekend,” one worried resident, Desiree Ralph, told the news station. She said insurance will not cover the damage from the erosion.

Every Bay Area county except Solano is under a flood watch from the National Weather Service through 10 a.m. Wednesday, and some mountain areas are expected to see as much as half a foot of rain.
